What is the Add Noise to Image?

The ByteTools Add Noise tool sprinkles random grain across an image at an intensity you choose. Noise can give digital photos a film-like texture, hide banding in smooth gradients, or add a gritty, analog mood to graphics and backgrounds.

  • Adjustable noise amount from subtle to heavy
  • Monochrome film grain or color noise modes
  • Regenerate button for a fresh random pattern
  • Great for film looks and reducing gradient banding
  • Live preview updates instantly
  • 100% private — images never leave your browser

About the Add Noise to Image

The ByteTools Add Noise tool sprinkles random grain across an image at an intensity you choose. Noise can give digital photos a film-like texture, hide banding in smooth gradients, or add a gritty, analog mood to graphics and backgrounds.

Choose monochrome grain for a classic film look or color noise for a more digital, speckled effect, and use the amount slider to dial the intensity up or down. A Regenerate button reshuffles the random pattern so you can pick a version you like.

The noise is generated locally on an HTML canvas in your browser and never during idle rendering. Your image is not uploaded to any server, so your photos and designs stay private on your device.

Frequently asked questions

How do I add film grain to a photo?

Upload the photo, keep color noise off for a monochrome look, and raise the amount slider until the grain feels right. Then download the PNG. Use Regenerate to try different random grain patterns.

What is the difference between color and monochrome noise?

Monochrome noise adds the same random value to all channels, producing neutral gray film grain. Color noise varies each channel independently, giving a speckled, digital-sensor look with colored specks.

Can noise hide banding in gradients?

Yes. A small amount of noise breaks up the visible steps in smooth gradients and skies, a technique called dithering. Keep the amount low so the banding disappears without the image looking gritty.

Is my image uploaded to add noise?

No. The grain is generated in your browser with the canvas API and nothing is sent to a server, so your images stay completely private.
